IIN that it annoys me when gay people sound gay?

Firstly, most gay men and lesbians sound exactly the same as heterosexual people and some heterosexual people have what you describe as a "gay accent" or speech patterns.

If you're expecting logic from someone who believes in demons you're wasting your time and energy and I'd suggest you stop trying and also stop blaming gay people's alleged speech patterns for your aunt's ignorance and bigotry, which are netirely her own responsibility.
